Monitoring system

Abstract

A monitoring system comprises a monitoring agent that keeps information related to a communication status of a low-power terminal that communicates under low power, and a monitoring device that monitors the status of the low-power terminal. The monitoring device includes a requesting unit that requests information related to the communication status of the low-power terminal. The monitoring agent includes a response generation unit that generates a response to the request from the monitoring device on a basis of the information related to the communication status of the low-power terminal, and a transmission unit that transmits the response to the monitoring device.

The invention claimed is: 
     
       1. A monitoring system comprising:
 a monitoring agent configured to keep information related to a communication status of a low-power terminal that communicates under low power; and 
 a monitoring device configured to monitor the status of the low-power terminal, wherein 
 the monitoring device includes
 a requesting unit, including one or more processors, configured to request information related to the communication status of the low-power terminal, and 
 
 the monitoring agent includes
 a response generation unit, including one or more processors, configured to generate a response to the request from the monitoring device on a basis of the information related to the communication status of the low-power terminal, and 
 a transmission unit, including one or more processors, configured to transmit the response to the monitoring device; 
 
 wherein:
 the monitoring device further includes a status determination unit, including one or more processors, configured to determine the status of the low-power terminal on a basis of information included in the response, 
 the status determination unit is configured to perform one or more of congestion determination, communication quality estimation, or obstruction determination as status monitoring of the low-power terminal, on the basis of the information included in the response, and 
 the status determination unit is configured to compute a resource utilization and an amount of interference with another system on a basis of an amount of traffic in a group and a time ratio of interference with another system, estimate a communication quality in the group on a basis of a communication frequency and a received signal strength in the group, and estimate a failure location in the group on a basis of the communication frequency and a packet loss rate. 
 
 
     
     
       2. The monitoring system according to  claim 1 , wherein
 the monitoring agent configured to group a plurality of the low-power terminals under singular address information, and 
 the response generation unit configured to generate the response to the request from the monitoring device in units of groups. 
 
     
     
       3. The monitoring system according to  claim 1 , further comprising:
 a setting and design control unit, including one or more processors, configured to perform one or more of controlling a setting in a relay device to which the low-power terminal connects, controlling a network design, or controlling a setting in the low-power terminal on a basis of a result of the status monitoring. 
 
     
     
       4. The monitoring system according to  claim 3 , wherein
 the setting and design control unit is configured to control one or more of a channel setting or a transmission output in the relay device, a communication route in a group including the relay device and the low-power terminal, or a setting in the low-power terminal according to a resource utilization, a communication quality, an amount of interference with another system, or a failure location. 
 
     
     
       5. The monitoring system according to  claim 3 , wherein
 the setting and design control unit is configured to increase or decrease a number of the relay devices or changes an arrangement of the relay devices to balance a communication load on a basis of one or more of a resource utilization, a communication quality, or an amount of interference with another system, as the controlling of the network design.
